GL effects have been investigated analytically in the strong field limit approximation [1]}, [2]}
for many different black holes in GR and alternative theories [3]}, [4]}, [5]}, [6]}, [7]}, [8]}, [9]}, [10]}, [11]}, but have also been criticized for their accuracy [12]}. In what follows we shall employ the continued fraction solution [13]}
adapting methods developed for Schwarzschild black holes [14]} to investigate GL by black holes in EQG.
